Abstract
Abstract A foam coated fiber core, the outer pores thereof being filled with substance of a solid, liquid of pressurized gaseous character in which the foamy coating acts as a carrier therefor, and in which the filler enhances the utility of the structure for many uses, such as uses of the fiber per se or as a carrier or dispenser of the added substance being carried therein.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
60 words
A fiber comprising a fibrous core substance having a foamed coating thereon selected from the group consisting of thermoplastic and thermo-setting resins, the foamy surface being interrupted with open pores of said foam, at least said open pores being filled with a member of the group consisting of a gas applied under pressure, a liquid, solid particles and mixtures thereof.
Claim 2
Dependent Claim
60 words
A fiber comprising a fibrous core substance having a foamed coating thereon selected from the group consisting of thermoplastic and thermo-setting resins, the foamy surface being interrupted with open pores of said foam, at least said open pores being filled with a member of the group consisting of a gas applied under pressure, a liquid, solid particles and mixtures thereof.
Claim 3
Dependent Claim
33 words
The coated fiber as defined in claim 1 wherein said gas is a reducing gas selected from the group consisting of hydrogen, methane, ethane, propane, butane, actylene, ethylene, propylene, butylene and carbon monoxide.
Claim 4
Dependent Claim
28 words
The coated fiber as defined in claim 1 wherein the gas is an oxidizing gas selected from the group consisting of oxygen, oxides of nitrogen and halogen gases.
Claim 5
Dependent Claim
26 words
The coated fiber as defined in claim 1 wherein the gas is a reactive gas of the group consisting of halogen acids, ammonia and boron fluoride.
Claim 6
Dependent Claim
29 words
The coated fiber as defined in claim 1 wherein the gas is substantially inert and is selected from the group consisting of carbon dioxide, nitrogen, fluoromethane, difluoromethane and helium.
Claim 7
Dependent Claim
35 words
The coated fiber as defined in claim 1 wherein the fiber pores are filled with solids of the group consisting of pigments, insecticides, fireproofing agents, catalysts, electro-conductive substances, detergents, absorbents, lubricants, filter aids and fertilizers.
Claim 8
Dependent Claim
40 words
The coated fiber as defined in claim 1 wherein the liquid is a member of the group consisting of a solvent, an insecticide, a lubricant, perfuming agent, detergent, a moisture absorbing agent, a humectant, solutions and mixtures thereof with solids.
Claim 9
Dependent Claim
33 words
The coated fiber as defined in claim 1 wherein the core material is a member of the group consisting of natural fiber, solid organic fiber, carbon fiber, metal wire, and synthetic inorganic fiber.
Claim 10
Dependent Claim
16 words
A matted and cohered integrally porous spongy body comprising the filled foam-coated fibers of claim 1.
Claim 11
Dependent Claim
78 words
The coated fiber as defined in claim 1 wherein said core material is electro-conductive, the pores of said coating are filled with an electrolyte in electro-conductive contact with said core and with the outer surface of said foamed coating and an outer coating of a metal having a different electro chemical activity than said core is plated over the filler foam in electro-conductive contact with said electrolyte filling thereby forming an electrolytic cell between said core and plating.
Claim 12
Dependent Claim
15 words
A brush comprising tufts of substantially parallel filled foam-coated fibers as defined in claim 1.
